Description

Technical Field

[0001] The utility model specifically relates to a sealing plug. Background Art

[0002] At present, the sealing plug is mainly used for cables in tunnels or cable wells, playing an insulating and sealing role at the end of the cable. The existing sealing plug is inconvenient to install and disassemble with the cable, resulting in low work efficiency of installers. Moreover, the sealing plug also has defects such as complex structural design and unreliable sealing performance. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a sealing plug with simple structure, stable and reliable performance, convenient disassembly and assembly, and reliable sealing performance.

[0004] To achieve the above purpose, the utility model adopts a sealing plug, which includes a sleeve body, a plug sealingly arranged at one end of the sleeve body, a locking sleeve arranged inside the other end of the sleeve body, a waterproof sleeve arranged inside the locking sleeve, and a locking nut arranged on the other end of the sleeve body and in limit fit with the locking sleeve. One end of the locking sleeve has a plurality of locking hooks distributed in a circular array. One end of the waterproof sleeve has a limit groove matching with the plurality of locking hooks. The plurality of locking hooks are engaged in the limit groove, and the limit fit between the waterproof sleeve and the plurality of locking hooks is formed.

[0005] The beneficial effect of the above structure is that the locking sleeve can press the waterproof sleeve against the outer peripheral wall of the cable, thereby enhancing the sealing effect between the waterproof sleeve and the cable, with better sealing performance. Moreover, during installation or disassembly, only by tightening or loosening the locking nut can the installation or disassembly of the cable and the sealing plug be realized, and the installation or disassembly is more convenient. Therefore, the sealing plug has the advantages of simple structure, stable and reliable performance, convenient disassembly and assembly, and reliable sealing performance.

[0006] Particularly, limiting inclined surfaces matching with the locking nut are respectively arranged on the outer walls of the plurality of locking hooks. A locking inclined surface matching with the limiting inclined surface is arranged inside the locking nut. When the locking nut is tightened, the locking inclined surface abuts against the limiting inclined surface, and the limit fit between the plurality of locking hooks and the locking nut is formed. The locking inclined surface of the locking nut can abut against the locking hooks of the locking sleeve, and the locking hooks can press the waterproof sleeve against the cable, which is beneficial to improving the sealing performance of the sealing plug.

[0007] Particularly, the other end of the locking sleeve is inserted into the sleeve body, and a limiting step abutting against the sleeve body is arranged on the locking sleeve. The locking sleeve is inserted into the sleeve body, which is convenient for the assembly of the locking sleeve and the sleeve body, and the assembly is more convenient.

[0008] In particular, one end of the plug has a screw part, a threaded hole is provided inside one end of the sleeve body, the screw part is connected in the threaded hole, and a sealing ring is provided between the plug and the sleeve body. The plug and the sleeve body are connected by threads, which facilitates the assembly of the plug and the sleeve body, and the sealing ring can enhance the sealing performance between the plug and the sleeve body.

[0009] In particular, a plurality of anti-slip ridges are respectively distributed on the outer peripheral wall of the sleeve body in a rectangular array. The anti-slip ridges can play an anti-slip role, thus facilitating the installation or disassembly of the sealing plug.

[0010] In particular, a plurality of anti-slip tooth grooves are respectively provided on the outer wall of the locking nut. The anti-slip tooth grooves play an anti-slip role, thus facilitating the installer to tighten or loosen the locking nut, and thus facilitating the installation or disassembly of the sealing plug.

[0013] Figure 3 It is an exploded view of an embodiment of the present invention. Detailed Implementation Modes

[0014] Such as Figures 1 to 3As shown in the figure, an embodiment of the utility model is a sealing plug, which includes a sleeve body 10, a plug 11 hermetically arranged at one end of the sleeve body 10, a locking sleeve 12 arranged inside the other end of the sleeve body 10, a waterproof sleeve 13 arranged inside the locking sleeve 12, and a locking nut 14 arranged at the other end of the sleeve body 10 and in limit fit with the locking sleeve 12. One end of the locking sleeve 12 has a plurality of locking hooks 121 distributed in an annular array. One end of the waterproof sleeve 13 has a limit groove 131 cooperating with the plurality of locking hooks 121. The plurality of locking hooks 121 are engaged in the limit groove 131, and form the limit fit between the waterproof sleeve 13 and the plurality of locking hooks 121. Limiting inclined surfaces 1211 cooperating with the locking nut 14 are respectively arranged on the outer walls of the plurality of locking hooks 121. A locking inclined surface 141 cooperating with the limiting inclined surface 1211 is arranged inside the locking nut 14. When the locking nut 14 is tightened, the locking inclined surface 141 abuts against the limiting inclined surface 1211, and forms the limit fit between the plurality of locking hooks 121 and the locking nut 14. The locking inclined surface of the locking nut can abut against the locking hook of the locking sleeve, and the locking hook can press the waterproof sleeve against the cable, which is beneficial to improving the sealing performance of the sealing plug. The other end of the locking sleeve 12 is inserted into the sleeve body 10, and a limit step 122 abutting against the sleeve body 10 is arranged on the locking sleeve 12. The locking sleeve is inserted into the sleeve body, which is convenient for the assembly of the locking sleeve and the sleeve body, and the assembly is more convenient. One end of the plug 11 has a screw rod portion 111. A threaded hole 101 is arranged inside one end of the sleeve body 10. The screw rod portion 111 is connected in the threaded hole 101, and a sealing ring 15 is arranged between the plug 11 and the sleeve body 10. The plug and the sleeve body are connected by threads, which is convenient for the assembly of the plug and the sleeve body, and the sealing ring can enhance the sealing performance between the plug and the sleeve body.

[0015] As Figure 1 and 2 shown, a plurality of anti-slip convex strips 102 are respectively distributed in a rectangular array on the outer peripheral wall of the sleeve body 10. The anti-slip convex strips can play an anti-slip role, which is convenient for the installation or disassembly of the sealing plug.
